The gaps between the joists is lined with blocks of concrete. The next step is to apply the screed layer over the top of the screed to ensure all joints and gaps are covered with a seal.

Here are some questions to Ask a Roofer Prior to deciding whether or not to Engage them.
A garage refurbishment doesn’t come cheap. It’s logical to inquire about a few things prior to the project to ensure you’re hiring a skilled tradesperson. These are the four questions that you must ask prior making a decision to hire anyone.
- How many years of expertise can you boast? Replacing tiles and slates is one of the fundamental abilities of a roofer. But, have they received any formal training or skills to put up a flat roof with the latest technology?
- Ask the roofing company to provide you with some references from jobs they’ve worked on. Contact the references and ask about their experience with hiring the roofing contractor.
- Be sure to request each roofing company for an exact estimate. It is not a good idea to get to receive a “roundabout number” on the phone. You need at least three precise quotes from three roofing companies.
- Be aware that the most affordable quote doesn’t mean it’s the best. If the price is significantly less expensive than other quotes this could be an indication of a lack of experience or the person has missed an important element of the task. Beware of sneaky and obnoxious sales techniques. The most popular selling techniques is to give an estimate of a small amount at the beginning, and then add additional things to the bill at the close.
Sometimes , there are valid motives for additional expenses that are not apparent until the project has begun. For instance, taking the felt from the flat roof, only to discover damaged and water-damaged plywood as well as damaged Joists. A skilled tradesman will know what is expected and inform you of the issue at the beginning.
